The Diamond T Motor Car Company manufactured automobiles until 1911 when the first truck, led to exclusive truck production and legendary status as style leaders. While "The Handsomest Truck in America" became their slogan, Diamond T also emphasized its engineering leadership. The White Motor Company purchased Diamond T in 1958, creating the Lansing Division which ceased production in 1967 when White's new Diamond Reo Division began producing Diamond Reo trucks.
